By the end of 2027 at the latest, the use of 2D codes at POS is to be implemented through suitable POS systems – a development that is being driven forward by GS1, retailers and many other international partners. For manufacturers, this means that they need to start adapting their marking systems at an early stage in order to benefit from the advantages and meet future retail requirements.
As a GS1 Germany Solution Partner, we are happy to advise and support you in finding the right marking solutions.
The most important information at a glance
This page provides a comprehensive overview of the most important aspects of 2D coding:
✔ Background & timeline for the changeover
✔ Implementation in production
Marking with 2D codes will become an important factor for cooperation with retailers in the near future – act now!
What are the advantages of using 2D codes?
For decades, the EAN/UPC barcode has ensured reliable processes in retail. However, it is increasingly reaching its limits: it can only encode one piece of information – the GTIN. Today, consumers and retailers demand greater transparency, traceability and digital connectivity.
Practical advantages of 2D codes
- Seamless traceability
- Encoding of variable retail data directly in the code
- Simplified inventory management
- Best-before date and recall checks at POS
- Improved protection against counterfeiting
- Improved customer experience and loyalty
- Easier data exchange between manufacturers and retailers
Technical advantages of 2D codes
- Expanded information capacity
- Static and dynamic data
- Improved compatibility through data identifier syntax
- Less space required compared to EAN barcodes
The implementation of 2D codes offers significant advantages: more data in a compact form, easy best-before date handling, better traceability and new digital applications for retailers and consumers. These possibilities are particularly attractive to retailers, who are investing heavily in the transition. Cash register systems are already being replaced by more powerful systems with optical 2D scanners.
What options do GS1-compliant code types offer?
2D codes such as GS1 DataMatrix or QR codes with GS1 Digital Link are the answer. They offer space for more data and connect products to the web, offering clear advantages over traditional EAN barcodes.
2D code variants
There are different types of 2D codes. Three variants are approved for open use at POS in accordance with GS1 standards:
- GS1 DataMatrix
- QR code
- DataMatrix
Manufacturers are free to choose which variant best supports their objectives.
What is the timeline for the transition?
2022 - 2027
Preparation and transition phase
- This phase is intended for gradual introduction: manufacturers, retailers and service providers are testing applications, hardware and software and adapting their processes to the new technology.
- In 2022, GS1 officially approved the use of 2D codes at the point of sale (POS). Since then, 2D codes (GS1 DataMatrix or QR code with GS1 Digital Link) can be used on products in addition to the classic EAN code.
- Dual marking as a standard: during this period, both the classic EAN/UPC and the new 2D code will appear on packaging. This ensures backward compatibility with existing POS systems.
End of 2027
Technological milestone
- By the end of 2027, all commercially available POS scanners worldwide should be technically capable of reading 2D codes – at least the GTIN must be able to be read and processed.
- This requires the widespread use of camera-based scanners and the updating of POS software for data interpretation.
Starting 2028
Free choice of code type
From January 2028, the decision will be up to the brand owner:
- Retaining classic EAN/UPC code or
- Switch completely to a 2D code as the sole code type on the product
Challenges of switching to 2D codes
The switch to 2D codes poses a challenge in terms of production technology. While static EAN codes are usually pre-printed on packaging, 2D codes require dynamic coding during the production process.
1. Resolution and readability of 2D codes
2D codes require a significantly higher resolution than linear barcodes so that the data they contain can be read. If the resolution is too low, readability is reduced and the error rate during data capture increases. In addition, material properties and special features of the production environment, such as extreme temperatures, dust exposure or humidity, can severely impair the print image.
Choosing the right marking technology is crucial here. Our systems deliver reliable results even under harsh industrial conditions.
2. Marking speed of 2D codes
In many industries, the speed of product marking is essential. On particularly fast production lines, it can be challenging to achieve sufficiently high resolution for 2D coding without slowing down production.
Our high-performance systems are specially designed for such requirements and guarantee precise coding at high speeds.
3. Integration into existing systems
The switch to 2D marking solutions requires careful planning and smooth integration. Companies must check whether their existing printers and systems meet the new requirements or need to be replaced.
Thanks to their modular design, our marking solutions can be flexibly integrated into existing systems with little effort and easily expanded as required.
Our technologies for 2D coding
Labelling systems for 2D codes
Our high-performance printing and dispensing systems enable labels to be printed with individual 2D codes in real time and applied precisely to the product.
- Very high cycle rates possible

- High-resolution small and large coding
- Compact integration into existing systems
- Suitable for almost all surfaces
Which marking solution is the right one?
The optimal marking solution for you depends on many factors: surface properties, production environment, existing systems, desired production speed, required resolution and much more.
Not every technology is suitable for every application – therefore, individual consultation is not only important, but essential.
